2 Portable, compact and robust Laser Shearography inspection system The FlawExplorer is an inspection solution for Non-Destructive Evaluation (NDE) and Quality Control applications, commonly used on composites and metallic materials. The system is based on Laser Shearography, an optical measurement technique which efficiently finds flaws where other methods don t. The Laser Shearography principle consists of interferometric comparison of a test object in two states, a neutral and a loaded one. Advanced software algorithms perform live image processing to identify variations in out-of-plane deformations between both states which in turn reveals surface or sub-surface discontinuities or anomalies by highlighting local weaknesses under certain load conditions. The non-contact method can accommodate test specimen with curved and complex surface geometries. Laser Shearography is widely used by leading manufacturers within Aerospace, Automotive and Wind Power, Marine, Aviation, Textile and similar composite related industries. This recognized NDT method is in compliance with the NAS410/EN4179 for NDT of composite structures. The FlawExplorer system consists of a sensor unit on a tripod, a controlling laptop computer with inspection/reporting software, cabling and power supply. The sensor unit is packaged in a portable, compact and rugged flight case, and the laptop and tripod are contained in individual carrying bags. FlawExplorer sensor unit with 4 or 8 laser diodes for inspection of areas up to 2 m 2 (20 ft 2 ) in one shot The system is available in two versions with 4 or 8 laser diodes that support inspection of areas from 10x10 cm (0.1 ft 2 ) up to 2m 2 (20 ft 2 ) in one shot. The FlawExplorer system can be configured with optional excitation modules based on heat, vacuum or vibration excitation respectively, making it suitable for a range of applications from QA in Manufacturing over Research to in-field Inspection operations. Seeing the invisible fast & cost-effectively Dantec Dynamics FlawExplorer inspection solution quickly detects and locates discontinuities in composites materials. The system systematically finds flaws like: Wrinkles, Disbonds, Delaminations, Cracks, Crushed core, Kissing bonds, Fluid ingress, Cracked cores, Repair defects, Voids, Foreign Objects, Impact damage (BVID s), etc. The FlawExplorer system inspects large areas over a short period of time. The result from a 2 m 2 (20 ft 2 ) inspection area is obtained in less than 30 seconds which makes it the perfect solution for time-sensitive, large scale industrial NDT related applications. For inspection of composite honeycomb, rubber, composite overwrapped pressure vessels (COPV), ceramics, fiberglass, carbonfiber & fiber-metal laminates, bi-metals, foamcores, leather, metal-metal bonds a.o. The FlawExplorer solution takes NDT & Quality Control to a new level featuring: Simple, easy to use inspection system that is ready to operate within seconds Fast inspection with real-time results Intuitive evaluation of structural integrity of composite components like ply drops, bulkheads, overlaps, splicers, stringers, ribs etc. Image filtering that produces clear, unambiguous and reproducible results Lower false calls and higher probability of detection (POD) rates Advanced customizable reporting functionalities PAGE 2

3 A state-of-the-art inspection solution that saves time and money Fast With FlawExplorer you can inspect large areas or high volume of test objects in a timely manner. This is a key benefit of Laser Shearography against alternative NDT methods. Once discontinuities are identified and located, other NDT techniques can be used for further evaluation and characterization. Easy Compared to other NDT inspection techniques the use of Laser Shearography requires no particular expertise. Thanks to the user-friendly inspection and reporting software any technician can easily acquire clear, reliable, and useful inspection data. In comparison with other NDT techniques, the FlawExplorer requires no collection of waste/couplant material and eliminates the need for health safe environments that are inherent to other NDT methods. Efficient While Ultrasonic testing (UT) and Thermography inspection techniques are struggling to access particular composites as GFRP and honeycomb, Laser Shearography has the ability to detect flaws in these types of materials thanks to the versatility in choosing the proper excitation method. Three optional excitation modules with thermal, vacuum or vibration loading make the FlawExplorer suitable for a wide range of applications. Cost effective The FlawExplorer helps expedite your complete NDT & Quality Control processes which in turn saves time and money. It can also be fully integrated with robotic systems to support automated inspection applications in production environments. This unique capability increases the throughput of a given inspection station and significantly decreases associated labor costs. Inspection processes can be optimized from R&D to production line environments. Inspection flows can be streamlined throughout the complete product lifecycle; on-site as well as in-field. Its capabilities of non-contact large area inspection makes Shearography the ideal technique for a solution in combination with an automated robotic inspection in a production environment Optional excitation modules Heat Excitation Heating excitation is widely used because of its ease-of-implementation and speed of acquisition. The ready to use heat excitation module comes with appropriate quartz heaters. These emit both in the visible and infra-red range in order to trigger best material response for a wide variety of material. The nature of the heat transfer allows the user to collect depth information. The heat excitation modules are fully controlled via the laptop. This allows the operator to create and implement automatic procedures where image acquisition and sample excitation are merged for reproducible and accurate results. Heat excitation is best suited for inspection of CFRPs laminates, metal sheets, thin GFRPs, etc. Vacuum Excitation Vacuum excitation is a mechanical excitation that aims to trigger defect indications by pulling the surface of the sample with a tunable vacuum. Our easy to use vacuum hood is specifically designed for this purpose. Vacuum excitation is best suitable for inspection of honeycombs, sandwich structures, foams, plastics, corks, etc. Vibration Excitation Vibration excitation is a dual purpose inspection method allowing defects to vibrate and thus deform. The method can also be used for Eigen Modes and Eigen frequency analysis. The frequency analysis application is primarily utilized in turbomachine testing. This can also be applied to any structural parts facing vibrations during their lifetime. The vibration excitation solution provides the user with a powerful piezo- PAGE 3
